The present invention relates to a tent of the kind wherein the tentskeleton consists of a plurality of tent poles interconnected at thetop, and wherein at the place of their junction a slidable vertical rodis arranged which engages the top part of the tent duck and serves forstretching the duck.

The main novel feature of the invention consists therein that the tentpoles each are made in two parts connected by means of a joint overwhich the duck is stretched, when the pole parts are turned out ofmutual alignment as the vertical rod is pushed upwards in counter actionto the duck.

It is preferable to interconnect the top ends of the tent poles in theknown way by means of a common connecting member in which the slidablerod is guided, and, according to the invention, the tent poles arepivotally connected to the said connecting member by means of two pivotsperpendicular to each other, one of the pivots being vertical when thetent has been erected. The erection of the tent will be greatlyfacilitated by thus providing a pivotal connection of the poles in twodirections perpendicular to each other An embodiment of the invention isillustrated by way of example on the accompanying drawings.

Fig. 1 is a perspective outside view of the erected tent, and Fig. 2 isa vertical section through the same, wherein for the sake of clearnessonly two opposite tent poles have been fully shown.

Fig. 3 shows, partly in section, an elevation of the upper connectingmember and adjacent parts.

Fig. 4 is a plan view of said connecting member adapted for 8 tentpoles.

Fig. 5 shows in elevation a detail of the lower pole part and the jointconnecting the two pole parts.

Fig. 6 shows in section an attachment provided with a spark arrester forthe passage of a smoke conduit through the duck The tent illustrated byway of example on the drawings is erected on a skeleton, consisting of anumber of tent poles, which below are pointed and driven into theground, and their tops are interconnected by means of a connectingmember, disclosed in detail in Figs. 3 and 4. Each tent pole consists oftwo parts, I designating the upper and 2 the lower pole part, which arepivotally connected by means of a joint 3 (Figs. 2 and 5). This jointconsists of two end pieces 5 and 6, of which one may be fork-shaped, andwhich are pivotally connected by means of a pin 4. The end pieces areprovided with bores for inserting the ends of the pole parts asillustrated. By this arrangement the tent poles may be folded togetherwhen the tent is being transported. To secure the joint 3 in adesiredangular position one or several holes may be provided in the 5 endpieces forming the joint for the insertion of a locking pin 3a or thelike.

The upper ends of the upper pole parts 2 are inserted in bores of endpieces 1 (Fig. 3), which by means of pins 8 are pivotally connected tocon- 10 necting parts I3 that by means of vertical pins i2 and nuts Mare pivotally jou'rnalled in a connecting member, which substantiallyconsists of a vertical sleeve l0 provided with a horizontal flange 9. Inthe flange 9 a number of holes II corresponding to the number of pins l2are provided. Either the end pieces I or the parts l3 may befork-shaped. Thus, the pole parts 2 are connected to the connectingmember by means of two pivots 8 and I2 perpendicular to each other,whereby the erection of the tent will be greatly facilitated.

A vertical rod l5, the upper end of which supports the centre of the topof the duck is slidably passed through the sleeve It). When the tent isto be erected, the rod I5 is pushed upwards, until the duck has beensumciently stretched. Thereupon the rod I5 is secured to the sleeve III.For this purpose, a number of holes l6 are provided in the rod l5 andtwo diametrically opposed 0 grooves I! are provided in the wall of thesleeve. When the rod occupies the right position a pin I8 is insertedthrough the hole nearest to the bottom of the grooves 17 so as to securethe rod. The lower edge of the duck is secured to the hooks 26 providedon the pointed ends 21 of the pole parts I.

The tent is secured to the ground preferably by means of ropes 28attached to the top of the rod l5 and tent-pegs driven into the ground,suitably with the aid of an intermediary rope 30 and a stretching member29 as illustrated.

When the rod I5 in the described way is pushed upwards stretching theduck, the latter exerts a counter pressure on the rod, which causes thepole parts I and 2 to be turned outwards about the joints 3, therebystretching the duck over the joints.

According to the invention, protection against moisture and draught iseffected by attaching a protecting cloth below the joints of the poleparts along the circumference of the tent to the inside of the duck, forexample by means of push buttons or by sewing so that the cloth willhang down towards the ground.

ground. The edge 2| may The protecting cloth is designated by l8 in Fig.2. The upper edge of the same is attached by means of push buttons 20 tothe duck at such a level that the lower edge 2| will rest on the ground,when the tent is erected. It may then as illustrated be folded towardsthe centre of the tent and may be attached to the be covered by a clothor tarpaulin 3| forming the floor in the tent. Between the suspendedcloth l8 and the duck stretched over the lower pole parts an insulatinginterspace 22 is formed which prevents the penetration of moisture anddraught.

According to the invention an interior ceiling in the form of a cloth 23is arranged, which is supported and stretched by the upper pole parts 2,the lower edge of the cloth 23 being attached to the inside of the duckI9 along its circumference and adjacent to the level of the joints 3 ofthe poles, for example by means of push buttons 24 or by sewing. At thecentre of the cloth 23 an opening is provided with a diametercorresponding to the width of the connecting member. By this arrangementa tight, warm and, above all, moisture-free roof of the tent is obtainedowing to the formation of an insulating interspace 25 between the outerduck 1-9 and the interior ceiling 23.

The tent according to the invention may also be provided with anattachment which makes possible the use of a fire-place, a furnace orstove in .the tent. For this purpose an attachment is secured to theouter duck for the pascured to the attachment.

sage of a smoke conduit from the fire-place. Such an attachment is shownin Figs. 2 and 6. 32 designates a furnace or stove placed inside thetent. Its smoke conduit 33 is passed through an opening 34 in the duck,suitably arranged between the fastenings of the cloth I8 and the innerceiling 23. Said attachment consists of plates 36 of refractorymaterial, such as asbestos, eternite or the like, which plates areprovided with openings for the passage of the smoke conduit and arrangedon opposite sides of the duck and connected by bolts 35 with wing nuts.On the outside of the duck a spark-arrester is se- The spark-arrestermay for example consist of four sheet metal plates 31 secured to theoutside plate 36 by means of hinges so that the plates 31 can be put uptowards each other, and connected, thus forming a spark-arrestertogether with a funnel 38 or the like inserted in the open end of thesmoke conduit, as illustrated in detail in Fig. 6. The spark-arrestermay, however, be of any other suitable design.

Having now particularly described the nature of my invention and themanner of its operation, what I claim is:

A tent having a tent skeleton consisting of a plurality. of'tent polespivotally connected at the top -to;a common connecting member by meansoftwopivots perpendicular to each other, one of said pivots being verticalwhen the tent is erected.
